Abstract
The utility model provides a dustproof structure for cold-extrusion granulation. The dustproof structure comprises a transmission shaft, wherein the transmission shaft is sleeved with a bearing, the bearing is sleeved with a bearing block, a dust cover tightly clamped with the transmission shaft through a transmission key is arranged on the transmission shaft, and the bottom of the dust cover is attached to the bearing and rotates along with the transmission shaft synchronously. The dustproof effect is further improved, an attachment ring is mounted in a gap between the bearing block and the dust cover, and a spring is mounted in a groove of the bearing block and pushes the attachment ring to be closely attached to the dust cover. According to the dustproof structure, the dust cover is added on the transmission shaft, so that dust in the air can be prevented from entering the bearing andcausingdamage to equipment, and the service life of the equipment is prolonged.
Description
Technical field
The utility model relates to mechanical transmission field, specifically a kind of cold-extruded granulation dustproof construction.
Background technique
In existing cold-extruded Granulation Equipments, because the environment of running is poor, dust disorderly flies.Corresponding dustproof just enough owing to lacking, dust easily enters and in bearing, causes device damage.
Model utility content
The utility model, in order to solve the problem of prior art, provides a kind of cold-extruded granulation dustproof construction, avoids dust to enter bearing inside, the life-span of extension device.
The utility model comprises transmission shaft, and on transmission shaft, cover has bearing, and on bearing, cover has bearing support, transmission shaft to be provided with by the dust-proof cover of driving key and transmission shaft clamping, and dust-proof cover bottom and bearing laminating, follow transmission shaft and synchronously rotate.
Further improve dust-proof effect, laminating ring is housed in the gap between bearing support and dust-proof cover, in bearing support groove, spring is housed, spring pushes away laminating ring and is close on dust-proof cover.
Further improve, described laminating number of rings amount is one.
The utility model beneficial effect is:
1, by increase dust-proof cover on transmission shaft, prevent that airborne dust from entering bearing inside and causing device damage, extend the working life of equipment.
2, bearing support plane can not contact with dust-proof cover, and dust can enter from gap, every gap, has further improved dust-proof effect by laminating loop resistance.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the partial enlarged drawing in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Structure of the present utility model as depicted in figs. 1 and 2, comprise transmission shaft 4, on transmission shaft 4, cover has bearing 6, on bearing 6, cover has bearing support 7, it is characterized in that: transmission shaft 4 is provided with the dust-proof cover 1 clamping by driving key 5 and transmission shaft 4, dust-proof cover 1 bottom and bearing 6 are fitted, and follow transmission shaft 4 and synchronously rotate.
Bearing support plane can not contact with dust-proof cover, dust can enter from gap, so increase by a laminating ring 2 in the gap between bearing support 7 and dust-proof cover 1, in bearing support 7 grooves, spring 3 is housed, spring 3 is close on dust-proof cover 1 laminating ring 2, further improves dust-proof effect.
The concrete application approach of the utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improve and also should be considered as protection domain of the present utility model.
